if($_POST[admin_user]!="" || $_POST[admin_pass]!="")
{
$conn=new mysqli("localhost","root","db_wlgl);
$conn->query("set names gb2312");
$admin_user=$_POST[admin_user];
$admin_pass=($_POST[admin_pass]);
$sql=$conn->query("call admin_regs('".$admin_user."','".$admin_pass."')");
$res=$sql->fetch_array(MYSQL_BOTH); //62行
if($res!=NULL){

session_register("admin_user");
session_register("admin_pass");
echo "";
}else{
echo "";
}
}

?>

在62行上面 echo $conn->error; 看看
